每一种语言和方言都有各自的语音格局。天津话的语音研究由来已久,前人的成果所涵盖的范围非常广泛,为我们的后续研究奠定了坚实的理论基础。同时,我们也看到,前人的研究方法大都是举例性的,少数是基于实验研究。基于此,本文对天津话的元音系统进行声学实验分析,以期更加全面、准确地反映和揭示天津话的语音系统。 Each language and dialect has its own voice pattern. The phonetic research of Tianjin dialect has a long history, and the scope of the achievements of its predecessors is very extensive, laying a solid theoretical foundation for our follow-up research. At the same time, we also see that the research methods of the predecessors are mostly examples, and the few are based on experimental research. Based on this, this thesis analyzes the vowel system of Tianjin dialect by acoustics experiment in order to reflect and reveal the phonetic system of Tianjin dialect more comprehensively and accurately.
